A film roll/bags-on-a-roll making machine includes a feeding unit for transferring a film/sheet of bags, a reel displacement unit for cycling a reel through a reel let-off position, a reel-supplying position, a film-rolling position and a film-cutting position for enabling the reel to roll up the film/sheet of bags into a film roll/bags-on-a-roll, a cutting device for cutting off the feeding film/sheet of bags from the film roll/bags-on-a-roll at the reel that is cycled to the film-cutting position, and a control unit for controlling the operation of the feeding unit, the reel displacement unit and the cutting device.

A paper tape turn-up construct including a cover flap and a multi-bend structure to both protect an adhesive layer and to build an optimized elevated structure to present the adhesive layer during initiation of the paper web turn up process. Methods and apparatus to form the constructs and apply the constructs to paper production equipment are also included. The multi-bend paper turn up construct includes layers of adhesive and pulpable substrate with strategically located release materials, such as silicon that enhance a bridging of a gap between a rotating paper web and an empty spool surface.

A rewinding machine includes a drawing assembly (1), a winding assembly, a core-change assembly (5), and pneumatic elements for interrupting the continuity of the ply at the end of a winding cycle, and for starting a new winding cycle.

An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

The application provides a winding device and a winding method. The winding device includes a feeding mechanism and at least two winding members, and the feeding mechanism is used to provide an electrode sheet and a separation membrane. The winding device is provided with a winding station and a non-winding station, and each of the winding members is movable between the winding station and the non-winding station. When one of the winding members winds the electrode sheet and the separation membrane for a preset amount of turns at the winding station, said one of the winding members moves from the winding station to the non-winding station. Said one of the winding members releases a part of the separation membrane wound on said one of the winding members when said another of the winding members winds the electrode sheet and the separation membrane.

Methods and apparatus to form elevated profiles in mounted turn-up transfer tapes for paper processing. In some embodiments, the transfer tape may be a combination of a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and an affixed cord or cordlike feature, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer. In some embodiments an elevated profile, similar to that resulting from the incorporated cord or cordlike feature, may be formed during the application of the transfer tape with specialized apparatus.

An assembly for entraining a cut end of a web in a fluid flow, the assembly comprising an arrangement for delivering a fluid flow proximal to an entrainment region where a web is cut. The assembly further has an arrangement for guiding the fluid flow and the entrained end of the web from the web entrainment region to a web delivery region.
